This note book will be used to record impedance tube data for the A50-150 plug.¶

This plug has 50% porosity with 150 vertical pores. Three different air backing rings will be used: 3, 4, and 5 cm. Data will be taken from 100 Hz up to 2000 Hz in 10 Hz steps. Time base files will be large enough to produce spectra with 5 Hz resolution.

We want to be able to calculate spectra that have some separation between measurement frequencies. For example, if we are taking data at every 20 Hz, it would be good to have digital spectra with 10 Hz resolution or less. The resolution of the digital spectrum is given by $$ df = \frac{Sample\ Frequency}{Number\ of\ Points}.$$ We can determine the Sample Frequency using the Preamble query. The fifth element returned by this query is the X increment ($dt$). The Sample Frequency will be $$ f_{samp} = \frac{1}{dt}.$$ The number of points of data needed to get $df = $10 Hz will be $$ n = \frac{f_{samp}}{10} = \frac{1}{10*dt}.$$
